CONVERTIBLE MUS IC STAND Filed May 51, 1944 2 Sheets-Sheet 2 INVENTOR.Payford Laserzfiee ATTORNEYS Patented June 24, 1947 UNITED STATES PATENTOFFICE 1 Claim.

The invention relates to a music stand, and more especially to aknockdown sheet turning music stand.

The primary object of the invention, is the provision of a stand of thischaracter, wherein its structure is such that the same can be knockeddown when not in use for the storage thereof in the least possiblespace, as well as the easy carrying thereof from place to place, thestand when set up will permit of the automatic turning of the leaves ofsheet music, thus eliminating the necessity of hand turning thereof.

Another object of the invention is the provision of a stand of thischaracter, wherein foot control is had of the sheet turner, therebyliberating the hands of the player, for such purpose, which might causeinterruptionin the playing of such music, the stand being novel in itsconstruction and arrangement of the component parts thereof.

A further object of the invention is the provision of a stand of thischaracter, which is simple in construction, thoroughly reliable in thepurposes intended thereof, strong, durable, readily and easily handled,susceptible of being knocked down and set up with dispatch with minimumlabor involved, and inexpensive to manufacture.

With these and other objects in view, the invention consists in thefeatures of construction, combination and arrangement of parts as willbe hereinafter more fully described, illustrated in the accompanyingdrawings, which disclose the preferred embodiment of the invention, andpointed out in the claims hereunto appended.

In the accompanying drawings:

Figure 2 is a perspective view of the music sheet turner release treadleof the stand.

Figure 3 is a sectional view taken on the line 3-3 of Figure 1 lookingin the direction of the arrows.

Figure 4 is a side view of the stand set up.

Figure 5 is a top plan view of the sheet turner.

Figure 6 is an enlarged sectional View taken on the line 66 of Figure 1.

Figure 7 is a fragmentary perspective view of the music rack couplingend of the stand column or post.

Similar reference characters indicate corresponding parts throughout theseveral views in the drawings.

Referring to the drawings in detail, A designates generally the uprightor supporting fixture. and B the rack fixture, respectively, of themusic stand constructed in accordance with the invention, these beinghereinafter fully described.

The fixture A comprises a tubular post or stem it, having fitted theretonear its lowermost end a plurality of swinging legs I I, which arepivoted at l2 to a bracket l3 arranged on the said post or stem i3, andthese legs II when spread contact with a foundation for supporting thepost or stem in an upright or vertical position.

In the uppermost end of the post or stem I0 is fitted a coupling stud l4having the fiat faced attaching ear or tongue l5 slightly angled to-thestud 14, so that when the rack fixture B is engaged therewith the latterwill slope in a forward direction when the stand is set up for use.

Formed on the post or stem ID; at its front are spaced hangers orbearings l3 slidably accommodating a shift rod H, which at its lower endis formed with a forwardly directed foot treadle 8. The rod H at theupper portion thereof is formed with a laterally directed latching arm19, which at its outer free end is provided with an upstanding latchingtip 20. The rod I1 is urged in a direction toward the rack fixture B bya coiled expansion spring 2| which surrounds the rod and is seatedagainst an abutment 22 on the latter and against the hanger or bearingl6 next to said spring. When the treadle I8 is depressed then the rod I1is lowered against the resistance of the spring 2! for the control ofthe latching tip 20 for a purpose presently described.

The rack fixture B comprises a center supporting column 23 having at itsback or rear face a loop-like keeper or coupling eye 24 detachablyreceiving the ear or tongue l5 for the separable fitting of the fixturesA and B together. At the lower portion of this column 23 are laterallyswingable rest pieces 25 for sheet music, and such pieces are pivoted at26 to the column 23 and cooperate with foldable and extensibletoggleacting back racking fittings 21 which are pivoted to the saidpieces 25 and column 23 as at 28 and 29, respectively. These fittings 2!serve as back rests for sheet music.

Swingable from one side to the other of the rack fixture B with relationto the column 23 thereof is a music sheet turner in the form of an openframe 30, which is hung on the column 23 by hinges 3|, these beingequipped with springs 32, so that the frame will be tensioned thereby toautomatically swing it from the right-hand side of the fixture B to theleft-hand side thereof, when such frame is latched at the right-handside of such fixture.

The latching tip 20 is loosely accommodated in a guideway 33 provided inthe rest piece 25 at the right-hand side of the fixture B to engage withthe frame 30 when moved to this side of such fixture so as to latch theframe in this position, the tip 20 being formed with a stop shoulder 34to limit the upward thrust of the said tip with relation to the framewhen engaged thereby. The treadle l8 when depressed retracts the tip 20for releasing the frame 30 so that through the action of the springs 32it will swing to the left hand side of the fixture, and thereby turningsheet music as may be clipped thereto. The frame 36 carries on oppositesides thereof sheet music clips 35, and likewise the fittings 21 carrysheet music clips 36 which are for the purpose of fastening sheet musicin place thereon.

The open frame 3%? permits the reading of a single sheet of musicfastened thereon at either side of such frame, it being understood, ofcourse, to accomplish this the said frame must swing to either side ofthe fixture B, to the right-hand or to the left-hand side thereof.

When the stand is not in use it can be knocked down, the fixtures A andB being detached from each other, and the swingable parts of each arethen folded, bringing the stand in a collapsed condition, resulting incompactness for storage or carrying purposes.

It is required that the frame 38 be latched at the right-hand side ofthe fixture, so that on release thereof it will be automatically shiftedto the left-hand side of such fixture, thereby eliminating the handturning of the sheet of music supported on such frame, the unlatchingofthe latter being had by depressing the foot treadle [8 by the user ofthe stand.

What is claimed is:

A stand of the kind described, comprising a tubular supporting fixturehaving a flat faced attaching ear formed thereon at an angle thereto, acoupling stud on the fixture, a, foldable sheet rack fixture having a,keeper on the rear thereof which is separably engaged by the attachingcar on the coupling stud, an en frame hinged central to the rackfixture, for sheet turning, tensioning means acting on the frame formoving the same from one side of the rack fixture to the other sidethereof, a foot treadle operated latch comprising a vertical rod formedwith a laterally directed triangular shaped latching arm, the outer freeend of which is provided with an upstanding latching tip movably fittedwith the fixtures for engaging and releasing this frame when undertension at one side of the rack fixture, means for limiting the movementof the latch relative to the frame, sheet clips carried by the foldablelegs on the supporting fixture, a bracket on the lower end of saidfixture, to which said legs are pivotally connected rack fixture andframe, respectively, and means for urging the latch in latching positionwith respect to the frame RAYFORD LISENBEE.
